There is no standard for this concept of "quartiles". The first quartile is simply the 25th percentile with the third quartile being the 75th percentile. Statisticians seem undecided over whether the quartile mark must be a data point or something inbetween. This is supported by the fact that if you ask for the third quartile (for example) using your TI-83 vs Casio 9800FX vs Excel spreadsheet, you will find that you get different answers. I think it's just most important to understand what it signifies rather than this formality. If it's for homework, then better ask about your teacher's preference.

If memory serves, by first principles means by the original way that your rules were derived. You know the power rule, the sine, cosine, tangent, log, exponential rules right? Who made these rules up? The answer: they were derived from first principles and for integrals many from the fundamental theorem of calculus. The first principles method is to use the very basic definition, that is, the derivative of any point is the change in y, delta y, divide by the change in x, delta x, all of this as delta y and delta x approach zero. What you get is an equation that looks like this: Take for example your function is sin x: [math] \frac{dy}{dx} = \lim_{\Delta x\to0}\frac{\sin{( x+\Delta x )}-\sin{x}}{\Delta x} [/math] Pheew, that took me forever to spit out in latex. Hardsss x_x Edit: yeap, long it was

As far as I know, there doesn't seem to be "The Equation" for this. Most of the studies are numerical, either by using computers to by brute force solve equations of gravitation, or empirical studies of supernovae. As for whether we can, I'm sure we can...with the right technology. I'm waiting for them to make the first experimental black hole (no joke, I read that black holes can be of nearly any size as long as the Schwarzschild condition is met)

Okay, in that case, this is going to be a calculus exercise. The easiest way to find the relationship is by taking the cross-section of the sphere and cone. Then you are back to two-dimensions on paper If it's any clearer, you can draw the cone upside down so that the base will be on the upper hemisphere of the sphere. Have the x-y axis running through the center of the sphere. Then increasing the angle from the x-axis you can see the base of the cone getting smaller while the height increases. The radius of the cone at any point is simply x = Rcos a, where R is the radius of the sphere and a is the angle. The height at any point is y = Rsin a (+ R, the other side of the sphere). Using the volume equation: 1/3 *pi * r^2 *h, plug everything and differentiate for the first maxima.

Alright, I'm a bit confused, but by your use of "circumscribed by", you mean that the cone is inside the sphere? Because if the sphere is inside the cone, and no height dimensions are given then the maximum volume is infinity. And since circumscribed usually refers to the smallest possible fit, trying to find the max of a min is a bit weird.

New Orleans Mayor C. Ray Nagin has just issued an official order of mandatory evacuation for Orleans Parish, effective immediately. http://www.neworleanscvb.com/static/index.cfm/action/group/contentID/256/sectionID/1/subsectionID/0/ According to predictions made previously, it seems like this may indeed be "the end" of New Orleans. A category 5 storm slamming directly into Lake Pontchartrain making it spill into New Orleans. Will there be much to salvage after the storm? http://www.time.com/time/reports/mississippi/orleans.html Being under sea level sure doesn't help. I just hope for the best to the people of that region.

My opinion on this would be to look for a college/university with the kind of atmosphere or culture that you think you would like. Campus visits would be the best for this. At the undergraduate level, I doubt there's much of a difference in what you will learn. They are based on similar cirricula and aim to give you a foundation in your field of interest... quite different from at the masters level where you want to make sure the university is with faculty who can guide you in the direction of your desired research. Ultimately, what I'm trying to say is that, good students make for a good university and not the other way around. Harvard is "successful" because they attract good students who would have otherwise been successful even if they didn't go to Harvard. Similarly, whether a university (esp. undergrad) is good has little to do with apparent fame. It's how hard you work there, and maybe how good their teaching staff is.

I think that for most cases it's not for the discomfort of others, but rather the "comfort" of the raper. There is also the S&M fetish stuff going on but...

are you sure the server/channel info is updated, cuz nobody's in there, and the channel's not even registered o_o

Yeah, it would be close to impossible to find a program that matches exactly your needs. If you do have programming skills, then the usual way to do things is to get a basic template from a forum or news publishing type of script, then hack it accordingly (giving credit to the original of course as stated in GNU licenses). I hope things work out for you though ^^;

The question doesn't concern the girl's height. Klaynos has already kindly written out the known and unknown parameters. 3 known and 2 unknown - which is solvable in this kind of kinematics problem. Simply plug the numbers into the equation. Additional info. The kinematics equations (a.k.a. the big four) that you should have memorized until you become familiar enough with these type of problems: http://www.glenbrook.k12.il.us/gbssci/phys/Class/1DKin/U1L6a.html

Looks like your requirements are just about the kind I need for my own personal webhosting needs. This falls under the budget web host category ($4.95-$7.95 per month). You should visit webhosting forums. A search of this on google will do the trick (webhostingtalk.com is my favorite). See what they have to see. In a nutshell however, you will find that it is best to pay rather than go free, because of the issue of uptime. Paid hosts tend to be up 99.99% of the time. Also, aim for the larger more established hosts. I've heard too many cases of people getting ripped off. Again, more of these details can be read on the web hosting discussion forum sites. Personally I'm using a $5.95 per month service and it's been great. No down times, no database screw ups, awesome script engine and great customer support. My personal list: Site5.com Lunarpages.com iPowweb.com They may slightly above your stated budget, but again it depends on how you value web hosting service ^^. Unless you are a completely unlucky customer, I doubt they will let you down. There are cheaper services and I leave that for you to judge. (in anycase often times budget hosts give customers who use alot of bandwidth or run intense scripts on their servers a hard time since this is seen as resource hogging on shared systems, but I think that doesn't apply to you)

Could you explain agian what you mean by "need to talk about everything about IC and programing and this chip and this and that". You need to know how integrated electronic chips are fabricated? I've never used this picaxe program however. It's hard to find a starting point on this if I don't know what you've been doing. It's really a vast subject in itself, and you can take 2-3 college courses just on IC technology with an additional 2-3 courses to build your foundations for the analysis of the technogy.

yourdadonapogos, beware! Martin is actually your physics teacher in disguise!

How are those questions even physics related. LOL, how much water do you drink in a life-time? Isn't that more like.... I don't know what it is.

The problem is we don't have mini-sized turbines. Not that I know of. I think a solar panel or a movement->electricity type of generator would work better. You know those watches that can run forever given you keep moving your wrist around.

What exactly is the question again? Examine the truth? Put aside the fact that it's a slightly elliptical orbit, yes you can say that the moon orbits around the Earth in circular orbits. Precisely stated, the Earth and moon revolve around the earth-moon barycenter. This center point is like the center of mass of the earth-moon system. Because the Earth is massive compared to the moon, this barycenter is within the Earth's radius, so it will seem like the moon is the only one doing the orbiting.

Hmm, I don't know of any formula for this (if one exists at all), but you can work on the equation: Power = Force x velocity as in the force on the paddle versus the velocity in which it is moving. The only problem I see is finding the force on the paddle wheel. What is the force required to anchor a paddle of 1 square meter in a river moving at that speed? o.o

Would it have sounded nicer is I added a smiley face to the end of that post (#6)? You sounded unsure in the beginning and I'm just glad you have a solid stance now that's all

There we go. Now you're making a statement.

The "speed of the sun"? As in the apparent speed of the sun across the sky? There isn't much of a meaning to that as far as I can think. It's more like the sun moves 180 degrees across the sky within a certain time frame. From there you can calculate the degrees/minutes/seconds transversed per second assuming uniform rotation of the Earth. As for what you did wrong, if you would elaborate on your experimental setup, because the numbers you have there are just unit conversions from the original 75mm/5min.

Haha, well that's why we have psychologists . Not all "psychos" (if I may) can treat themselves.

I've done alot of read up on the nature of homosexuality back in my highschool days. I remember debating on the whole issue of gay marriage. It appears that it is more likely than not that homosexuality is genetic, so you are in effect born gay. It's like transexuals; ever heard of being born in the wrong body? Anyway, I have not heard of the story from the bi-sexual side. I think there is somewhat of a choice here. If you feel attraction to the "proper" sex, then to a certain extent you are capable of being "normal". It seems like they are choosing to do the abnormal. Again I have no evidence, but my comments are that I would attribute this to a psychological abnormality rather than genetic as with the homosexual case.

I'm a strong believer in the Buddhist principles of life and thought. I would love the opportunity to read this book. Although I don't know what it's all about now, I certainly am open to think that principles taught in religion that have a tadbit of "truth" in a scientific context.
